The URX_CF heat recovery unit series is the mono-bloc solution designed for the installation requirements typical for public spaces like bars,
restaurants, offi ces, meeting rooms.
The URX_CF units combine in one mono-bloc unit, besides the fan, fi lter, and heat recovery sections, a heat pump refrigerant circuit
with scroll compressors of high output and low noise.
The supply air is heated or cooled, based on the season, through the heat pump refrigerant circuit located within the unit and
charged with refrigerant R410A. All this allows to have a complete unit, with the automatic operation in each season and capable of
combining the required space ventilation requirements with effi cient heat recovery.
The careful design of the machine combines very compact dimensions, which permit easy installation in false ceilings, with an
excellent accessibility for maintaining all the internal components.
Characteristics
VERSIONS
• Standard horizontal configuration
5 sizes complete with temperature controller and ready for installation.
PANELS:
• Self-supporting sandwich panel 0 .78 inch thick in galvanised steel for internal and external surfaces with injected polyurethane insulation
(density 2.5 lb/ft3).
HEAT RECOVERY:
• Cross flow plate heat exchanger in aluminium with outputs over 50% in winter conditions.
FILTERS:
